Abstract
The present invention relates to a sunglass attachable to a pair of glasses at a later stage, which sunglass is reliably attached to the glasses and in which a sunglass plate is stably held at a flipped position, and also relates to an attachment fitting thereof. The attachment fitting includes a shaft strip, a base, a base contacting strip, an elastic body, and an elastic receiving strip. The base is rotatable with respect to the shaft strip, and the base contacting strip and the elastic receiving strip are fixed so as not to rotate with respect to the shaft strip. With the elastic force of the elastic body, the base contacting strip is pressed towards the base and the base contacting strip and the base are engaged, thus allowing the sunglass plate attached to ends of the shaft strip to be freely raised upwards and lowered downwards and to be freely stopped in stages.
